Question

a bacterium was discovered in several hot springs. the temperature of the springs can range from 50 to 80 degrees celsius. scientists investigate an enzyme from this bacterium. they set up the data table show to record their results. which question could be answered using the data to be collected? how does the enzymess shape change over time? how does temperature affect the reaction rate of the enzyme? how does substrate concentration affect the reaction rate of the enzyme? how does the active site of an enzyme change with different temperatures?

Explanation:

Step1: Analyze the variables in the table

The table has columns for different temperatures (5°C, 22°C, 37°C, 60°C, 80°C, 100°C) and rows for reaction rates at different times. The key variable being tested across the tubes is temperature.

Step2: Relate the variable to the questions

• The first option "How does the active site of an enzyme change with different temperatures?" is related to temperature (the variable in the table).
• The second option about substrate concentration - there is no data on substrate concentration in the table.
• The third option about enzyme's shape change over time - the table has reaction rates at different times but the main variable across tubes (which would answer a question about a factor affecting the enzyme) is temperature, not time - related shape change (the time - related data is within each temperature condition).
• The fourth option about temperature affecting reaction rate - this is exactly what the table's temperature variable (across tubes) can be used to answer as we can compare reaction rates at different temperatures.

Answer:

How does temperature affect the reaction rate of the enzyme?
